I don’t think there will be a part 2, but I would like to add another route at some point in the future.
However, I’ve currently prioritized working on my main project. So likely after the next release of Coffee Story. Maybe 2.
If you want, I can give you some suggestions about the fourth route. I read that you were having problems with coming up with more puzzles and such. For example, burn the heart.
Everyone starts freaking out, thinking that they have to kill one of them; when in all actuality it means burn a heart shaped locket that you find in the back pack. I don't mind helping.
If you do make a fourth route, have it be focused on Anne but keep the ending; I liked it as its perfect for a suspenseful ending!
If you need help coming up with ideas for that, then let me know and I can help with that as well! I'm a writer in my spare time.
